SAMUEL E. ROSE, NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO EUGENE MUNSELLi & CO., 01 NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

INGANDESOENT GAS- AMP.

To all whom it may concern Be. itknown that I, SAMUEL E. Rosn, a citizenof the United States, and a resident of the city, county, and State ofNew York, (whose post-oflice address is 68 Church street, New Yorkcity,) have invented a new and useful Improvement in Incandescent Gas-Lamps, of which the following is a specification.

The object of my invention is to provide a device of this class in whicha chimney is supported by a mantle ring so that at all times, andespecially during the shipping and erecting of the mantle on the burner,the mantle will be protected against all injury, and when in use theglobe will be protected by the chimney from the intense heat of themantle. These, and other objects are accomplished by my invention, someembodiments of which are hereinafter set forth.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which Figure1 is a sectional view showing a burner of the inverted type providedwith one form of my improved chimney and chimney support. Fig. 1 is asectional view showing a detail of construction. Fig. 2 is a sectionalView, taken on the line 2-2 of Fig. 1, looking in the direction of thearrows. Fig. 3 is a sectional View, taken on the line 3-3 of Fig. 2,looking in the direction of the arrows. Fig. 4 is a sectional view,taken on the line 44 of Fig 2, looking in the direction of the arrows.Fig. 5 is a sectional View, taken on the line 5-5 of Fig. 3, looking inthe direction of the arrows. Figs. 6 and 7 show a modified constructionof chimney, Fig. 7 being taken on the line 77 of Fig. 6, looking in thedirection of the arrows.

provided with the usual curved pipe 2 on which is mounted a shade holder3 adapted to hold a shade, not shown, and below the shade holder is asuitable burner tip 4 provided with the conventional sockets 5,preferably. three in number, which are adapted to receive and supportthe lugs 6 of a mantle ring 7, in the conventional manner. The mantle ismounted on this ring 7 in the Specification of Letters Patent.

usual way so that no further description is necessary. The lugs 6 havenot only an in-- wardly extending end adapted to engage the sockets 5,but also the conventional prongs 9 which are engaged by the chimneyholder 10. This chimney holder 10 is preferably made in the form of aring with a depending flange 11 from which run radially and inwardlyextending cars 12 from which extend vertical spring catches 13 which areadapted to take over and under the parts 9 of the projections 6 of thering 7. A chimney 14 is made cylindrical in form and fits snug withinthe flange 11 and is held thereby. This chimney may be made in any ofseveral ways, but it is preferably made of mica bound at its top andbottom by an nular bands 15, the lower one of which is provided withsuitable prongs 16 which take over and under a disk 17 so as to hold thesame in place at the bottom of the chimney. After this disk 17 is madeto fit snug, as shown in Fig. 1, suitable ventilating holes 17 are madeabove the level of the same and in the chimney 14 so that enough air maybe had for the purposes of combustion. In the modification shown inFigs. 6 and 7 the disk 17, at the bottom of the chimney 14 is supportedby means of suitable hooked wires 18 which run from a centrally locatedeyelet 19 to the edge of the disk 17 and thence vertically and upwardlyto suitable eyelets 20 located at suitable points in the chimney 14, andthese wires 18 pass through them and then pass downwardly so as to formhooks whereby the disk 17 is properly supported. In this modification ofmy invention the disk 17 is made of smaller diameter than the chimney 14so as to leave a suitable air space for the purposes of combustion.

In view of the foregoing, the operation of my improved device will bereadily understood. Assuming that the burner 4 is ready to receive amantle, the mantle 8 is put in place, together with its chimney 14 andchimney support 10, the fingers of the operator being pressed againstthis support 10 as he places the mantle in position, whereby it is putin position without being handled or in any way injured. Once inposition it is placed where it has to be lighted properly from above,and cannot be lighted from below, and it is placed without injury sothat its life will be as long as possible.

When it is used up it may be readily re moved and another mantleinserted in its" place. Should it be necessary, the chimney 14 may beseparated from'the holder 10 and washed and then restored without in anyway injuring the mantle or any han-' dling of the same. While I haveshown and described one embodiment of my invention, ity is: obviousthatit is not restricted thereto, but is broad enough to cover allstructures that come within the scope of the annexed claim.

; Having thus described my invention, what I claim is a In a device ofthe class described, a man- :Witnesses: a Y
